UNITED STATES PATENT EEIGEK GEORGE WILLIAMS, OF MYSTIO RIVER, ASSIGN OROF ONE-HALF HIS RIGHT TO FREDERICK A. HOLMES, OF STONINGTON,CONNECTICUT.

IMPRQVEMEN'I'I IN CAR-AXLE BOXES.

Speeication forming part of Letters Patent No. 169,664, datedNovember-9, 1875; application tiled september 25, 1875.

To all whom it may concern Beit known that I, GEORGE WILLIAMS, of MysticRiver, in the county of New London and State of Connecticut, haveinvented certain new and useful Improvementsin Oar Journal-Boxes; and Ido hereby declare that the followingis a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it pertains to make and use-the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this spec iflcatiom The nature of my inventionconsists `in the construction and arrangement ot' a car-axle journaLbox,as will be hereinafter more fullyset forth.

In the accompanying drawing, Figure 1 is a longitudinal vertical sectionof my car-axle journal-box. Fig. 2 is an end view of the same. Fig.- 3is also an end View with the outer collar removed. Figs. 4, 5, 6, and 7are detached views of parts thereof. i

A represents the box proper. B is the journal; C, the bearing-block forthe same, and E the wedge-piece as generally used ou top of thebearing-block. The outer end of the box A is curved substantially asshown in Fig. l, and terminates in a round opening at, A', on theinterior of which, at the extreme edge, are formed four or moreinclinedor wedge-shaped ribs or l'langes, ct a. D is the cover to'closethe opening A', said cover being provided on its inner side with four ormore hook-shaped lugs, b'b, to catch on the flanges ct a, and therebyform a right or left screw for fastening the cover. On the inner end ofthe box A is a collar, G, provided' with a circular inside col 1 lar,G', fitting tight around the journal, the two collars overlapping eachother, as shown `in Fig. l. The outer collar G is on each side providedwith a vertically-slotted projection,

d, fitting on the square head of a bolt, f, which is secured to the box,and the collar is held up by means of springs e inserted in the slots`of the ears d above the bolts, as shown in Fig. 2.' Within the box Anear the inner end is a slide, H, fitting tight tothe journal, formingwith the-slot in the box a tight-tting oil-joint. Under the lower end ofthe slide H is a spring, h, to raise the slide and take the weight fromthe journal. Between the slide H and the col larsG G' there is left aspace, t', on the journal, which is to be stuli'ed or packed with wool,asbestus, or other suitable material to keep the oil in the box in andthe ldust out. This packing is set up at the bottom by means of afollower, J, and set-screw I operating thereon.

The great trouble in car-axle journal-boxes now in use is, that bythelateral motion of the journal in the box, and the rising of the journalcaused by the wearing" of the seat, the dust Works into the box and onthe bearing, causing friction and heat, wearing the metal or seat andjournal, and as the dust can get in, of course the oil escapes. Thisdifculty is entirely obviated by my invention.

Having thus fully'described my invention, what I claim as new, anddesire to secure by Letters Patent, is-.

The combination, with the box A and journal B, of the collar G withslotted. ears d d, interior collar G', square-headed screws f, andsprings e, substantially as and for the purposes herein set forth.

In testimony-that I claim the foregoingV as my own I ax my signature inpresence of two witnesses.

GEORGE WILLIAMS.
